ABSTRACT:
A portable weighing device comprising two laterally displaced, electrically connection and rigidly aligned weighing modules is disclosed that permits convenient weighing of the mobility-disabled while occupying a conventional manually-operated wheelchair supported by two front caster wheels and two rear main wheels. The portions of the weight of the wheelchair supported by each wheel is successively summed and the tare is electronically subtracted. The weight of the occupant is then displayed. Accordingly with the weighing device wheelchair users can be conveniently weighted at rehabilitation centers, physician's offices or hospital clinics, or alternatively can weight themselves at their residence. The weighing device can be folded for carriage or storage.
